PLOW.

Specification of Letters Patent.

Patented Jan. 28,1913.

Application filed June 3, 1912. Serial No. 701,280.

To all whom it may concern: V

Be it known that I, ANDERSON L. Roenns. a citizen of the United States,residing at Carbon, in the county of Eastland and State of Texas, haveinvented certain new and useful Improvements in Plows; and I do declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to improvements in plows.

()ne object of the invention is to provide a plow having an improvedconstruction of jointed beam and means for adjusting the sectionsthereof for the purpose of regulating the draft of the plow and to varythe angle of the plow standard and point whereby the latter will becaused to plow the ground more or less deeply as desired.

Another object is to provide a plow having a pivoted clevis and meanswhereby the same may be adjusted to change the side or lateral draft ofthe plow.

Vith these and other objects in view, the invention consists of certainnovel features of construction, and the combination and arrangement ofparts as will be more fully described and claimed.

In the accompanying drawings; Figure l is a side view of my improvedplow. Fig. 2 is a top plan view of the same. Fig. 3 is a vertical crosssectional view of the front end on the line 33 of Fig. 1; Fig. i is anenlarged central longitudinal sectional view of a portion of the plowbeam sect-ions showing more clearly the manner in which the same areadjusted.

Referring more particularly to the drawings 1 denotes my improved plowthe beam of which comprises a front section 2 and rear section 3, saidrear section being preferably eXtended and curved downwardly to form thestandard l of the plow. The rear and front sections of the beam arehingedly connected by a pivot bolt 5, and in forming the joint theforward end of the rear section of the beam is reduced onits oppositesides to form-a tongue 6 which is loosely engaged with a notch or recess7 in the inner end of the outer section of the beam as shown. The tongue6 and the adjacent parts of the front section of the beam have formedtherein alined bolt holes with which is engaged the pivot bolt 5 whichhingedly connects the sections of the beam together.

Secured to the lower end of the standard t is the plow blade 8 which maybe of any form or construction and to which are secured in any suitablemanner the handles 9 of the plow. The handles 9 are braced and securedto the standards 4 by suitably arranged brace rods 10.

Secured to the front section 2 of the beam adjacent to its pivoted rearend is an up wardly projecting beam adjusting lever 11 in which isformed a guide slot 12 and a guide passage 13. On the lever 11 andspaced a suitable distance from the connected end thereof is anapertured guide lug 1a with which and with the guide passage 13 isslidably engaged a pawl 15 on which is ar ranged. a stop collar 16. Onthe pawl 15 between the stop collar 16 and the guide lug 1% is arrangeda coiled spring 17 the pressure of which is exerted to force the pawlinwardly. The pawl 15 is extended and has on its inner end a handle 18whereby the pawl may be retracted against the pressure of the spring 17.

Fixed on the upper side of the rear section 3 of the beamadjacent to itspivotal connection with the front section is a segmental rack 1%) whichprojects upwardly through the guide slot 19 in the opposite rear end. ofthe lever and with the teeth of which is adapted to be engaged the rearend of the pawl 15 when thelatter is projected by the spring 17.

By providing the front section of the beam with the lever 11 andproviding the pawl and ratchet connection between said lever and therear section of the beam it will be obvious that said beam sections maybe adjusted to different angles with respect to each other therebyregulating the draft of the plow and also varying the angle at which theplow blade or point enters the ground, which will cause the point orblade to plow more or less deeply according to the amount of adjustmentgiven to the sections of the I inner end of the segmental plate, theouter portion of which is ta ered and has therein a draft eye 22 to whicis ada ted to be secured any suitable form of dra devices (not shown).In the curved outer edge of the segmental plate forming the clevis is aseries of rack teeth 23. Slidably mounted in suitable brackets 24secured to one side of the beam is-a pawl 25 the outer end of which isadapted to engage the teeth on the inner end of the clevis whereby thelatter is locked in the positions to which it has been adjusted. On thepawl is arranged a stop collar 26 between which and one of the brackets24 is arranged a coiled spring 27 the pressure of which is applied toforce or project the pawl forwardly to engage the end thereof with theteeth of the clevis. Connected to the pawl is a pawl retracting rod 28which extends back alongside the beam to a point within convenient reachof the driver or operator of the plow whereby the-pawl may be retractedand disengaged from the teeth of the clevis to permit the latter to beturned on its pivotal connection with the outer end of the beam wherebythe side draft of the plow is varied.

In order to permit the clevis to be turned to vary the draft, Ipreferably provide a clevis adjusting rod 29 the forward end of which isloosely connected with an eye 30 in one end of the clevis, while theinner end thereof is attached to an operating lever 31 pivotallyconnected to one side of the inner section of the plow beam withinconvenient reach'of' the driver or operator whereby when the pawl 25 hasbeen disengaged from the teeth of the clevis in the manner described thelever 31 may be adjusted to turn the clevis to the desired extent inwhich position the same is again locked by the pawl 25 through thepressure of the spring 27.

From the foregoing description taken in connection with the accompanyingdrawings, the construction and operation of the invention will bereadily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of the invention as claimed.

Having thus described my invention, what I claim is; j 4

1; In a plow, agbeam composed of two sections hingedly connected, thefront end of which is adapted to move in a vertical direction, and meanssecured to the front end of said beam and adapted to be laterally movedin respect to the draft end thereof, and means for operating the latterin both directions from the rear end ofthe beam.

2. In a plow, a beam formed of a rear and front section pivotallyconnected, a segmental rack bar secured to the'rear section, a leverrigidly secured to the front section and provided with a curved 'slotthrough which the rack bar freely passes, a pawl carried by said leverand movably secured thereto and in parallel relation therewith, saidpawl having an upturned end for manipulating the same and an operatingend for engagement with said rack bar, a guide lug forming a part of thelever through which the pawl slidingly passes, acollar fixed to saidpawl, and a coil spring disposed between said collar and lug, wherebythe pawl isheld in engagement with the rack bar, the operating end ofthe pawl being located in advance of the manipulating end of the lever,whereby the front end of the beam may be readily manipulated andadjusted.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

ANDERSON LAYNE ROGERS.
